The year is 2029. Five years ago, South Korea attempted to send an expedition to the Moon, but the rocket exploded shortly after launch, so high hopes are pinned on the new mission. The spacecraft, which has already been placed in lunar orbit, comes under the influence of a strong solar wind; a fuel leak occurs, followed by an explosion that results in the deaths of two of the three crew members. The flight control center is urgently calling upon a long‑disgraced former leader who knows the operation of space systems better than anyone else and can help the remaining astronaut complete the mission and return to Earth alive.
